Course Abstracts:

Advanced ESD/EMI Auditing Techniques (1 credit) FC363

Instructor: Al Wallash

In order to solve today’s ESD problems, ESD auditing must provide data on not only the static charge and voltage on tooling and devices, but also the transient voltage, current and electromagnetic field interference (EMI) up to at least 1 GHz. This practical course will teach how to use a variety of charge, current, voltage and E-field probes to understand the ESD/EMI threats during processing of ESD sensitive devices.

This tutorial provides an overview of the joint HBM standard by the ESDA and JEDEC which introduces numerous options to set up the test plan for HBM qualification. The options include high pin count devices, reducing relay capacitance from the tester and two pin testing. There was a need to explain these options in detail and a user guide has also been released to provide further guidance in these tests. This tutorial will attempt to cover the user guide and will give examples of setting up the different tests plans that utilize the options outlined in the standard.

CDM Testing Essentials (1 credit) DT200

Instructor: Alan RighterCertification: DST

This tutorial will give students the fundamental information required to quickly learn the CDM testing method on commercial CDM test equipment and the associated oscilloscope / metrology chain information needed to capture and interpret CDM waveforms. Additional information on CDM testing standards and their hardware differences, package effects on the CDM waveforms and package limitations will be covered. Students will also be introduced to the background information needed in understanding CDM failure modes along with test program output failure types needed to understand the effects of CDM testing.

Changes to ANSI/ESD S20.20 from the 2007 version to the 2014 version (1 credit) FC171

Instructor: John Kinnear

This presentation will describe the changes to ANSI/ESD S20.20. The reasoning behind the changes will be addressed and questions will be taken from the audience. The actual presentation will be 30 to 35 minutes with time at the end for open discussion.

Charged Board Events: A Growing Industry Concern (1 credit) GP230

Instructor: Terry Welsher

A charged board stores much more energy than a device (IC) because its capacitance is many times larger. In fact, the charge (energy) transferred in the event is so large that it can cause EOS-like failures to the components on the board. In this seminar, this board-level ESD event will be compared with the component level CDM ESD event. The waveforms from both ESD events will be compared and it will be shown that for the same voltage, the current in the board-level ESD event will be much higher than that from the chip-level ESD event. A summary of literature and industry data will be given. It is suggested that failure analysts give stronger consideration to these types of board level events before assigning an EOS diagnosis to the failure. This will support more effective root cause analysis and prevention of these failures.

Charged Device Model Phenomena, Design and Modeling (3 credits) DD200

Instructors: Melanie Etherton, Mike ChaineCertification: DD

This course teaches the fundamental concepts required to design ESD protection for Charged Device Model events and provides insight into the specific physical aspects of the phenomenon that need to be considered to verify the CDM ESD protection structures and concepts with circuit simulation.

The fundamental physics of the CDM event, such as charge and discharge physics, characterization methods, and failures mechanisms are covered in this tutorial. The basics of CDM ESD design strategies for IOs are discussed and methods to verify the robustness of these ESD structures for the CDM target level. Circuits and strategies for protecting power domain signal crossings are introduced and methods are discussed for verifying the effectiveness of these solutions. Insight into CDM circuit simulation requirements and physical aspects of the CDM ESD phenomenon that are important for reproducing the event with circuit simulation for failure debugging or ESD strategy verification are provided.

Cleanroom Considerations for the Program Manager (3 credits) FC110

Instructor: Christopher LongCertification: PrM

Many industries require "Clean Manufacturing", however with clean manufacturing also come requirements for lowered humidity levels, process-required insulators, ultra-clean surfaces, processes which involve product movement, and a lack of naturally occurring ions. All of these can pose challenges from an electrostatic generation and discharge perspective. It is critical for those who work in industries that require clean manufacturing to know how to control static charge generation in and around contamination and ESD sensitive products. The purpose of class is to provide background on cleanroom/clean environment fundamentals, means of control and measurement of such environments, and methods for controlling/eliminating electrostatic discharge in clean manufacturing processes.

Compliance Verification: Pitfalls of Auditing (1 credit) FC211

Instructor: Ginger Hansel

Accurate data is the foundation of effective ESD Program Management. Therefore, it’s important to have confidence in the measurements. Choosing the correct type of equipment for each measurement is also important and not always obvious.

The class will cover the correct use of static locators, resistance meters, event detectors, and how to use ionizers effectively. We will discuss the various pitfalls of commonly used instruments, and the invalid test results that can result. For instance, static locators can yield totally invalid readings when used incorrectly due to voltage suppression. What you learn will help you avoid frequently encountered auditing problems, and improve your compliance verification program.

This course will focus on the grounding and material requirements of ESD Controls in Automated Handling Equipment (AHE) for prevention of CDM and MM type damage to ESD sensitive devices. Design methods and material selections that provide effective ground paths through the assembly will be introduced. Test methods used to qualify the design will be discussed. Students will also become familiar with different types of plating and practices to provide effective designs.

Developing a Compliance Verification Program (1 credit) FC241

Instructor: John Kinnear

Compliance verification is one of the required elements in the ANSI/ESD S20.20 standard. Without periodic verification of the ESD materials used within an Electrostatic Protected Area (EPA) programs can degrade over time. This course will cover some of the items that need to be considered for a successful compliance verification program.

Topics covered in this program include,• What is a compliance verification program?• What is the difference between product qualification and compliance verification?• How does the ESD program manager determine the frequency of testing?

As part of the course, common ESD control items will be covered and how to do the testing efficiently and to meet the requirements of ANSI/ESD S20.20 and TR53. Questions can be submitted in advance to be answered as part of the course.

Device Stress Testing Standards Update (1 credit) DT202

Instructor: Alan RighterCertification: DST

This tutorial will describe major updates to the HBM and CDM Device Stress Testing Standards. After a brief introduction to both the Joint ESDA/JEDEC HBM and proposed Joint CDM Standards and the motivations for their developments, specific improvements in each standard (relative to their previous separate ESDA and JEDEC standards) will be described. These stress testing method improvements will be supported by test setup and measurement data where appropriate. Examples of the HBM and CDM stress testing procedures (setting up, measurement) using the new updated standards will be given. After taking this course, students will have the basic understanding of the improvements in the Joint HBM and proposed Joint CDM Standards and a basic understanding of how to apply these improvements to existing testers for stress testing.

Device Technology & Failure Analysis Overview (3 credits) FC215

Instructor: Jim VinsonCertification: PrM

This tutorial provides an overview of the device technology used to provide ESD protection, ESD protection techniques, and Failure Analysis (FA) techniques to debug non-working ESD protection. This class does not go into the depth necessary to equip the student to be an ESD Protection Designer or an ESD Failure Analysis Engineer. It does familiarize the student with the terms and concepts of ESD protection and FA to allow the student to interact and understand the work being done by the Designer or Failure Analyst. After completing this tutorial the student should be able to understand the basics of device ESD protection design and some of the trade-offs inherent in that process. The student should also be familiar with the most commonly used failure analysis techniques and tools used to identify the root cause of an ESD failure. The topics covered include: the three most common ESD Models: HBM, CDM and System Level (IEC); characteristics of ideal ESD protection; ESD failure analysis schemes; key characteristics of real ESD protection; failure analysis flow; failure analysis tools and how they are applied to ESD failures.

ESD Device Stress Testing is known to benefit at least three areas: qualifying the product, simulate failures from factory or field, and to improve the design of the product. Three ESD models (HBM, MM and CDM) are used to simulate failures and to differentiate between the different types of ESD failures and also to differentiate the ESD type failures from EOS-type failures. Even though there are no Failure Analysis standards for ESD, there is enough archived data, published data and experience to show correlation exists between the ESD Stress testing types, the physical failure types and the eventual root cause. The type of equipment required to get to the physical failures and see the failures will be emphasized. The class will show how to correlate each ESD model stress testing results to the physical failure type and the physical failure location on the die. A real example will be used to show how the ESD stress testing lead to the root cause of a field failure.

Electric Fields: Practical Considerations (1 credit) FC261

Instructor: David E. Swenson

ANSI/ESD S20.20 requires that process essential insulators with a measured electrical field strength of >2000 volts at 1 inch be kept a minimum of 12 inches from ESD susceptible items. Just what are the practical considerations of this statement? What about electrical fields of 1999 volts at 1 inch? Can items with lower field strength be ignored? Is there a size consideration when it comes to charged objects? If so, what is the size of a charged object that imposes a risk? What is the magnitude of an electrical field that should be of concern in a process?

This tutorial presents information from a recent investigation of electrical field strength that was conducted to support a revision of ANSI/ESD S20.20. The audience should gain a practical perspective of size and distance as related to electrical field strength. Additionally, the audience should be able to relate the information in this tutorial to their own process environments to help estimate the risk of damage to sensitive items that may be grounded within the electrical field from process essential insulators.

Electrostatic Attraction (1 credit) FC260

Instructor: Carl Newberg

This training will cover the causes and effects of electrostatic attraction (ESA) and the solution to ESA problems in a variety of industries. Electrostatic attraction problems plague industries from photographic to medical and electronics. In the electronics industry alone, electrostatic attraction problems can be found in disk drive assembly, wafer fabrication and PC board assembly. The solutions to these problems can be found by applying a combination of the fundamentals of electrostatics and contamination control. An overview of clean rooms, ionization, materials and the control of static electricity will be presented. Real world problems and their solutions will be discussed using case histories.

Electrostatic Calculations for the Program Manager (3 credits) FC380

Instructors: Leo G. Henry, Terry WelsherCertification: PrM

This on-line tutorial is a four part series on Electrostatic Calculations. The material included is the same as is included in the full tutorial usually presented at the EOS/ESD Symposium or ESDA Regional Tutorials. The four parts focus on the basic calculations and techniques of use to the Program Manager and the ESD engineer. The content is at the introductory high school or college pre-calculus and introductory college physics level set in the context of electrostatic discharge and its effects. Each part also includes an additional review of the mathematics used in the practical calculations.

This course will outline the fundamentals of ESD phenomena and the methods to control the effects of ESD for safe manufacturing of IC devices. The training material will include the nature of ESD transients, their impact on the IC devices, common methods to test for ESD at both the device level and the system board level, and the overall protection techniques. Finally, the course will review the advances in IC technologies that lead to future challenges for ESD development and the resulting important technology roadmap established by the ESD Association.

Handling of customer rejects has become more and more challenging over the years in view of EOS. Unlike ten years ago today most customers are asking for an EOS statement containing a conclusive and comprehensive explanation of the failure scenario that has finally resulted in an "EOS-like" damage and this EOS statement has to be discussed on much higher technical level. On the other hand still today there is not much awareness on the customer side that most "EOS-like" failure signatures do not allow a comprehensive conclusion to the origin of EOS and so the final root cause cannot be evaluated without customer’s support. But in order to be prepared to conduct a successful root cause analysis together with customer the supplier is committed to build up an EOS knowledge base for both internal and external needs. The seminar should deliver insight in today‘s handling of customer rejects in terms of EOS and all the background that is necessary to be successful in that important topic – complemented with a few demonstrative examples.

ESD Standards Overview for the Program Manager (3 credits) FC210

Instructor: David E SwensonCertification: PrM

The ESD Association’s introduction of the Program Manager Certification curriculum has created a need to modify the Standards Tutorial that has been presented for a number of years, mainly to help individuals prepare for the iNARTE Engineering and Technician Exams. Currently, many of the ESDA Standards and Standard Test Methods are discussed in depth in the individual tutorials related to the specific subject matter. This Standards Tutorial provides an overview of all the Standards, grouped into common test types, based on measurement probe and test instruments. A common methodology is used in this tutorial to cover the requirements, applications and specifications for each Standard and Standard Test Method.

Advances in semiconductor technology development have enabled significantly more complex integrated circuits (IC). This complexity has driven an increased number of pins on an IC package. These higher pin count IC packages have led to a significantly higher ESD qualification cost and complexity. However, many designs often have a large number of common or "cloned" IOs which enables the possibility of using statistical sampling schemes to help improve ESD qualification in an efficient manner without reducing the overall quality of the stress test method. This tutorial will discuss the details behind the changes that are being made to the joint ANSI/ESDA/JEDEC JS-001-2012 HBM Test Method, including the definition of cloned IOs, the procedure for sampled testing of cloned IOs and a clear statistical justification behind these changes. The tutorial will conclude with a discussion of possible future opportunities in both HBM and CDM test methods for even further improvements in using statistical sampling techniques.

In addition, the proper use and testing of smocks and ionization will be covered.

Fundamentals of Failure Analysis (1 credit) DT142

Instructor: Jim VinsonCertification: DST

Failure analysis is the diagnostic tool of the semiconductor industry. It is the semiconductor equivalent of forensic science. Failure analysis unravels the mystery behind how and why a part failed, determining the root cause and corrective actions needed to prevent future failures. This tutorial is targeted toward people doing stress testing on a daily basis where failures are generated and need to be analyzed to determine what failed and how to improve a part’s robustness. The focus will be on failure analysis methods and tools use to analyze failures resulting from ESD, TLP, or latchup related stressing but will be applicable for wearout as well as infant mortality related failures as well. The tutorial will cover the 5 basic steps necessary to perform a failure analysis: 1) Information Gathering, 2) Failure Verification, 3) Failure Site Localization, 4) Root Cause Investigation, and 5) Corrective Action.

Fundamentals of System Level Testing (1 credit) DT130

Instructor: Mike HopkinsCertification: DST

Integrated Circuit ESD Fundamentals (3 credits) DD103

Instructors: Alan Righter, Warren Anderson

This three hour tutorial is focused on integrated circuit ESD fundamentals, and is targeted for two audiences: for the IC circuit designer who needs knowledge of how ESD can affect IC design, test, handling and system use; and those engineers wishing to be introduced to IC ESD, as a primer to further study.

Integrated ESD Device and Board Level Design Part (2 credits) DD231

Efficient ESD design for system level ESD can only be achieved if board and device level protection circuitry coincide. The purpose of this tutorial is to develop an understanding of board/IC interaction under IEC 61000-4-2 testing conditions and to discuss useful design strategies supported by appropriate tools. This is meant to be beneficial both for ESD engineers of ICs and board designers responsible for EMC/ESD compliant design of the system. While it has clearly been pointed out that even elevated IC level HBM targets are insufficient for achieving the required IEC 61000-4-2 ESD level, more awareness has to be developed for the detailed turn-on and clamping behavior of IC level and board level ESD protection components. High current characterization of board protection and IO circuit by TLP is a first step. This enables the board designer to assess the behavior of IC pins and select appropriate board protection elements. The design optimization should be based on high current models of board components and IC IOs and the numerical simulation of the protection network under ESD conditions. Finally, various test methods are available to evaluate the efficiency of implemented protection on board level quantitatively

Ionization Issues and Answers for the Program Manager (3 credits) FC120

Instructor: Arnold SteinmanCertification: PrM

The primary method of static charge control is direct connection to ground for conductors, static dissipative materials, and personnel. But a complete static control program must also deal with isolated conductors, insulating materials, and moving personnel that cannot be grounded. Air ionization can neutralize the charge on insulated and isolated objects. It does this by charging the molecules of the gases in the surrounding air. Whatever charge is present on objects in the work area, it will be neutralized by attracting opposite polarity charges from the air. This webinar will present the information needed to use ionizers to solve problems caused by static charge. It is a basic course on ionizers, providing an introduction to their use, as well as advanced application information.

Overview on Efficient and Reliable System-Level ESD (1 credit) GP330

Instructor: Mirko Scholz

The ongoing integration of system functionality in ICs requires that IC pins comply with system-level ESD specifications. Often without knowing the final application, component-level ESD designers need to provide designs which are also robust to system-level ESD stress. In contrary, system-level ESD designer usually have no access to information about the component-level ESD protection design. To overcome this situation, the system-efficient ESD design (SEED) has been proposed. This online seminar introduces and evaluates two main system-level design methodologies: datasheet-based design and SEED (System-efficient ESD design). Different examples illustrate which data is used as design input and what are the limitations of each methodology. It is shown how component-level ESD testing and transient simulations (SPICE and mixed-mode) enable an efficient and reliable system-level ESD protection design.

Packaging Principles for the PrM (3 credits) FC200

Instructor: David SwensonCertification: PrM

Shipping electronic parts within a factory, to another factory, distributor, or to an end-user has always been an area of uncertainty within the manufacturing process.

To provide clear-cut information on what type of controlled packaging should be used in any situation, the ESD Association released a comprehensive revision of the obsolete industry standard EIA 541-1988. The newer document, ANSI/ESD S541, is the focus of this inclusive session. It provides information and guidance, as well as material specifications, to assist in the design and implementation of a packaging plan for use within an ANSI/ESD S20.20 based ESD Control Program. Current and newly released test method standards suitable for packaging material evaluation will be described. Course credit applies to the ESD Program Manager Certification curriculum. Previous attendance at the "ESD Basics" and "How To’s…" tutorials are highly recommended.

The idea of this tutorial would be to tackle the practical aspects of designing and testing for latch-up robustness. From a design perspective, layout floor-planning, design rules, and EDA checks will be covered. From a test perspective, standard DC latch-up testing as well as transient latch-up testing (including system-level ESD, cable discharge, and the evolving transient latch-up standard) will be covered. Finally, real world latch-up failures and diagnoses will be presented.

Susceptibility Testing of Devices and Systems (1 credit) DD/FC132

Instructor: Michael Hopkins

There is a disconnect in the EMC (Electro Magnetic Compatibility) world between system manufacturers testing systems for upset and device manufacturers testing devices for failure. Some system level manufacturers are pushing device manufacturers to test semiconductor devices using system level compliance standards – specifically, IEC 61000-4-2 for ESD (Electrostatic Discharge). Product manufacturers would like to believe that if devices are qualified to IEC standard(s); finished products will likewise be qualified. Unfortunately, there is a fundamental difference between system level and device level testing; fortunately however, this difference can be bridged using new susceptibility scanning techniques on the board or device. Until now, EMC and ESD susceptibility testing at the device level has not been done. In this course, we will cover scanning methods (using a magnetic field noise source and probe) that allow identification of susceptible devices in a system, sensitive areas/pins of devices and associated circuitry.

This tutorial is intended to help those tasked with ESD testing of products and devices to understand how testing is done and how failures are defined at the System Level. It will provide detailed information on IEC 61000-4-2, the most commonly used ESD test at the system level, as well as specific information about Automotive, Medical, and Avionics test requirements. The course will answer common questions regarding test set-ups, test points and procedures and address key issues, including the use of IEC 61000-4-2 for testing devices now being required of some device manufacturers.

TCAD Fundamentals (1 credit) DD117

Instructor: Kai Esmark

TCAD (technology computer aided design) tools have become an indispensable utensil for the semiconductor industry. The possibilities to analyze, predict and optimize a certain semiconductor device behavior through modeling semiconductor fabrication (Process TCAD) and semiconductor device operation (Device TCAD) are countless. This includes the area for ESD and Latch-up development, as early access to fundamental device parameters under very high current density and high temperature transients is the key to overcome the conceptual problem of concurrent engineering for ESD engineers.

This tutorial serves as a basic introduction into TCAD tool chain including process and device simulation as well as the creation and integration of compact models for mixed more simulation. Focus points are the capabilities but also limitations of these tools, like the requirements for a 2D/3D simulation approach and the validity of the models describing the fundamental physics, especially in the high temperature regime.

TCAD Methodologies for Industrial ESD Design (1 credit) DD205

Instructor: Vladislav Vashchenko

This seminar provides a comprehensive overview of the TCAD methodologies and best practices for industrial ESD design. Both the generic simulation workflow review and the classification of the most representative cases are covered. The advanced capability of mixed-mode simulation approach with device, circuit and process parameterization is demonstrated. Fabless and fab-light industry trends are addressed by overcoming the critical requirement of the well calibrated process simulation flow. The overall goal of the seminar is to add a new dimension to the standard R&D methodology and make it directly useful to a broad audience of ESD device, circuit and application engineers rather than corporate TCAD experts.

This tutorial will explain what Transmission Line Pulsing (TLP) is and how it can be used for ESD design and development. Taking accurate TLP measurements is important thus how TLP systems make measurements and produce IV plots will be reviewed. The IV plots provide very valuable device parameters that are key to understanding the DUT being stressed. The tutorial will also explain the parameters that can be extracted from those IV curves. Finally typical equipment used in TLP systems will be reviewed.

Ultra-Sensitivity Trends and CDM (1 credit) GP241

Instructor: Ted Dangelmayer

The electronics industry faces a double challenge: increasing use of ultra-sensitive devices and lack of experience with the Charge Device Model (CDM). This class will give you the background to understand the challenges and prepare to meet them. Case studies will illustrate how CDM failures can persist even with a robust HBM program in place. A series of photographs of common CDM issues in manufacturing will enable students to visualize how to implement CDM controls. A brief summary of the work by the Industry Council on ESD Target Levels will be included.

Use of the Digital Sampling Oscilloscope for ESD Measurements (3 Hours) DD122/FC122

Instructor: Larry Levit

The digital sampling oscilloscope (DSO) finds application in measuring waveforms that occur infrequently or only once. Its sophisticated calculation and display capabilities give it utility for factory ESD, as well as, its role in monitoring ESD immunity waveforms for both component and system level ESD.Understanding instrument performance issues is important for proper use. DSO bandwidth and the sampling rate are often used interchangeably, although they serve completely different purposes. The bandwidth, sampling rate and memory depth of the instrument must be specified for the intended application. DSOs also have display modes which can hide undersampling artifacts and lead to incorrect conclusions. Selecting the appropriate display algorithm is important for both cosmetic purposes and to achieve correct results from the instrument. Also important for the proper use of any oscilloscope are selection of the input impedance and the setup of the trigger. For a DSO, the pretrigger value must also be set. In some cases equivalent time sampling can be used but in most ESD measurements, single shot acquisition is required. Finally, for ESD applications on the factory floor, there are a variety of probes that are used. These include, wide bandwidth current probes, clamp on current probes, single ended and differential voltage probes, as well as, high frequency antennas.

VF-TLP, An Introduction to Capabilities and Applications (1 credit) DT212

Instructor: Mirko ScholzCertification: DST

VF-TLP stands for Very Fast Transmission Line Pulsing. Standard TLP uses typically 100 ns long pulses. It allows the device characterization in the HBM time domain. VF-TLP uses pulses with a duration of a few nanoseconds and faster rise times than standard TLP. It allows the device characterization and (transient) voltage and current measurement in the CDM time domain. This tutorial explains the VF-TLP measurement setups, equipment options and how the extracted data is interpreted. Several examples explained how the VF-TLP setup parasitic are de-embedded and applied to the obtained "raw" measurement data. The goal of the tutorial is to enable the operator to deliver high quality measurement data to the ESD protection designer.
